Looking at the list of materials in front of him, Feng Xiyan read it out loud, "The basic materials we need are wood, stone, rammed earth or adobe bricks, glutinous rice, tiles, and river sand."
Noting them down on her phone, Bai Hanyun asked, "You guys don't use iron or steel pipes to reinforce the foundations and walls?"
When she asked this, Feng Xiyan looked surprised and explained, "Fairy Bai, bronze, iron, silver, gold, and jade are controlled materials. Only the imperial court and the emperor have authority over them. It's a capital crime to use iron for building houses. As for steel, we don't have it in the Yu Empire."
Now it was Bai Hanyun's turn to be surprised. She paused for a moment, then asked, "Feng Xiyan, if I send you some iron and steel pipes, would you use them to strengthen the buildings? Would it be alright?"
